The Rothmans is based on a standard racing model and Pidcocks had the decals and powder coating done. As far as I remember, the Rothmans just had the hubs and rims in red and blue, the fuel tank was powder coated in blue and the decals for the mudguards. The bike for sale has lots of extras added by the owner, which bring it up to a similar spec to the Repsol, but there not factory carbon parts and it doesn't have the carbon headlight. I really don't think you should be worried about comparing it to a Repsol, if you like it then that's good enough. They will ride just the same, unless the throttle body is a dual map, this and a mitani header and silencer will make a slight difference. The one for sale seems a good spec. This is what I would call a proper Rothmans Rep and what Pidcocks should have done.

Do you know anyone that has a 4rt, if so, borrow the complete fuel system(tank,hose and injector) and try it on yours, if it starts, it's a fuel problem. Next thing to do then, strip the fuel tank, drain the fuel out of the pump and filter, clean everything, power up the fuel pump to see if it's working, flush everything with fresh fuel. If your fuel tank/pump has rust in it, that could be your problem too.

DMTB is the first thing with a Laia Sanz map, change the gearing to 42/9 or 43/9, put a mitani titanium front header pipe 27mm and mitani titanium silencer (saves over a kg and better smoother power, especially with a DMTB and a 280 kit, oh, and I know where there's a mint set up for sale, if your interested). As it's an 06, you might want to put a mitani clutch in to get a smoother action.

Why do you want, need the 300 kit, are you a very good expert or better? I know a very good expert rider that rides a standard engined 4rt and wins most often at club level, on a standard 250. But if you wanted to go bigger, the 280 kit would be more than suffient, without the need to modify the crank cases (which is what I believe you have to do with a 300 kit). Future sell a bigger rad for reason ;0). I'm no expert on this subject, but I know quite a lot 4rt owners, but don't know anyone who has done a 300 kit. (Munch on here is your man, for info) No Grip in mud, well that's debateable, depends on what setup there running really, there are bikes that are a bit better, but if they were c###, no one would be riding them, would they, there are plenty of good clubmen riding them. (It's a shame there isn't someone like Sam Connor or Dan Thorpe riding one next year, as they would show what the bikes really capable of). Is it a bike your buying, or are you moding one you own already? The best mod on an older 4rt is a dual map throttle body, but if you can afford a new bike, buy the new 260, you won't regret it ;0).

Make sure it's got a bigger radiator, they run hot.

Hi Andrew, you use a jubilee clip to hold the fuel pump on, in between the two alloy pins. You may find that the rubber gasket doesn't fit properly (future quality parts!) so you will have to trim a couple of the little tabs off. I'll get some pics on here today sometime. Andy

Speak to Steve Saunders, surely he'd know if any are left.

Montesa, You do not take the clutch off for oil changes, you have to remove the left cover for a filter chage, which is easy, otherwise, both transmission and engine oil have normal drain bolts. The 260 is superb, has been vastly improved and is nothing like the old 250 and would be great for what you want. The beta is a great bike and feels really nice, but the suspension is nowhere near as good as the Monts, the Beta can be a bit temperamental , due to its overly complicated fueling/cold/hot start system, whereas the Mont has fuel injection which makes it very easy. If your buying new, buy with your heart, either one, you'll enjoy. Can you not arrange a test ride on both and make your own mind up, (it's a lot of money, so try before you buy)

If you love bike racing, watch it, I've just watched it at a mates, FB :0)

Had one of those, (actually, had 3) brilliant bike, the red was the best colour, of all the 315's.

BVM, "no worries, we'll send you some replacements" thanks Rick :0) By the way, the ones causing problems are the new type, with the flatter red cap. It maybe just be me, but the magnets don't appear to be as strong as the one I had before.

Wired into original using torpedo connectors and same earth, but I'll have a look at that later.

Fitted jitsie lanyard kill switch to my new Mont 260 and most times I use it, it doesn't stop the engine, sometimes it takes about 10 seconds and a few times, it's actually continued to run even though the lanyard has been removed. I've taken it apart (easy) to see if there are any obvious problems, but it's still happening. It's not an isolated case either, because my Bro's, which was bought at the same time is doing the same thing. The worrying thing is, we bought them, so as to have that instant "engine stop" when it was needed, but it fails to do this. On my previous 4rt, I had a Leonelli Branded lanyard and never had any problem. Has anyone else had any problem with there's?

Phil, gearing is very high as standard, 10/41, most riders around hear run 9/43 or 9/42 (100 link chain 9/42) which slows the bike down in first gear, but still allows you to do most sections in 1st or 2nd gear. I think a lot of the expert riders prefer standard gearing. Looking forward to seeing what you have done.

Phill, try 9/42 sprockets for the gearing.

Braktec, it's AJP renamed I think, and it's anew design.

Their not breaking any laws, the dealer is selling at the RRP set by the importer, if they wish to sell at a lower price they can, but if demand outstrips supply, then they have no reason to do it. What they cannot do, is sell it above the RRP. They are also doing very low finance on them if that's how you want to buy a new bike (for anyone wanting to buy a bike on finance, (don't know the rate), then surely the Mont is the bike to do it on, due to there quality, reliability and resale, for 3 years use) and discounts are available on multiple sales ;0), but not a lot. Just spent fifteen quid on having this done.

I think it's unfair of you to high jack this thread, if you want to have a say about noise, start a thread please.

09 and after had the major improvements, forks are different (adjusters) mapping and complete exhaust system is different and quieter. Be careful about year dates, as some 08 were sold in 09 but don't have the updates. Apparently the frame was changed too, but I don't know if that is correct. Also watch for the old "school" ones that were used at the training schools and were rented out for the ssdt etc, some have been well used. There are plenty of good ones about, just depends how much you want to spend.

I think you may be referring to pre 09 4rt's, after 09, they were much quieter and don't have the crack of the older ones. I have never had anyone, say that my 4rt is too noisy. Have you ever been to a pre 65/twin shock event, some of those bikes are loud and not just the 4 strokes. Anyway, to answer the OP questions, the standard is the quietest, looks good, but is about twice the weight of the Mitani system. Termignoni is the most expensive and I'd say probably the loudest, but looks the best, but if you bin it, you could wreck it, whereas the others have covers. Neither the Mitani or Termi have been designed to inter grate with the new rear mudguard, the mitani would require either the carbon cover moding or the mudguard/air box shield cutting down, you'd also need the old pre 09 silencer/mudguard mount bracket. The Termi also requires this bracket. (Touch the pic for full image)

Just got in from my first ride, have to say, the difference between my 2012 and the 260 Race Rep are: The suspension: feels slightly faster with a bit more spring from my 12, but still has that superb Showa plush feel. Brakes: very good consistent strong feel, without being too sharp. Clutch: very smooth, I don't think it felt that different from my 12, a little more progressive maybe, due to the new master cylinder (I know the pre 09 were a bit sharp) but I really liked my mont clutch anyway. Engine: (I have changed the gearing from standard 10/41 to 9/42) from the bottom end, power is very smooth, definitely softer than before, but there is more torque at the bottom end too, so as you ride across a camber and then turn up a bank, traction is very good, it pulls very smoothly but also builds to a lot more torque, without loosing traction (it was wet tacky, claggy, clayish type soil covered in wet leaves). The front end feels lighter, my thoughts are that this is partly due to the suspension settings and partly due to better engine torque at the bottom end, this makes it even easier to lift the front with throttle. The bank I rode up was fairly steep and about 20 feet, I was very happy with how the bike felt like. Engine braking, it's still a four stroke, but engine braking is less than before, when you shut the throttle, it rolls on, there's still some engine braking, but I'm sure people coming from a 2 stroke will appreciate it. I think the biggest benefit from less engine braking is when you shut the throttle and then open it again, on a slippery surface. I cannot tell you what the power is like at higher revs, as most my riding today was at the lower end,( running it in). Overall: feels really NICE, powerful and lighter, not much lighter, (it isn't) but the front end does feel lighter, everything feels familiar, but better, traction is great and it looks REALLY NICE :0). The bike looks smaller and shorter (it's not) but the rear mudguard is much narrower and a bit shorter. The fuel tank is still quite big (I had a mitani flat tank on the 12) but looks much nicer and sharpens up the new up to date look. I am SO HAPPY :0) And so is my Brother, below. :0)

My favourite rider in WTC is Albert, but I've never bought a sherco. One of my favourite riders in the uk is joe baker, never bought a notagas either, although if I didn't buy Hondas, that would be first choice. I have had fantics, yamahas, beta and a scorpa/Yamaha. But now I'd only really buy Honda/Montesa with a 4t.

I can't believe anyone buys a bike, based on what the factory riders are riding. Surely just about everyone buys on either recommendation, test ride, or a particular make preference. All the modern bikes are good, some are maybe a bit better, but they all have a different feel, which is a big part of deciding what you like.

I think you'd probably find the 125 as an entry bike, is subsidised by all the other bikes in the mx range.
